Is it possible to decrypt a text file encrypted using PHP without using PHP itself, as asked in the forum thread?

The issue is that decrypting a text file encrypted using PHP without using PHP itself can be challenging because PHP uses its own encryption algorithms and methods. One way to solve this issue is to use a common encryption algorithm that is supported by other programming languages, such as AES. By encrypting the text file using a common algorithm, it can be decrypted using other programming languages. 

// Encrypting a text file using AES encryption
$plaintext = file_get_contents('file.txt');
$key = 'my_secret_key';
$iv = 'my_iv_parameter';
$ciphertext = openssl_encrypt($plaintext, 'AES-256-CBC', $key, 0, $iv);
file_put_contents('encrypted_file.txt', $ciphertext);

// Decrypting the encrypted file using AES decryption in PHP
$encrypted_text = file_get_contents('encrypted_file.txt');
$decrypted_text = openssl_decrypt($encrypted_text, 'AES-256-CBC', $key, 0, $iv);
echo $decrypted_text;
